Radiolysis of trioxalatoferrate (III) ions in aqueous solution - the effect of initial concentration of solute and dose rate

During the radiolysis of deoxygenated aqueous solution of trioxalato ferrate (III) ions at pH2, after the initial building up of Fe(II) concentration, its steady-state is reached. Both the initial rate of production of Fe(II) and its steady-state concentration increase with the increase in dose rate as well as with the initial concentration of the ferric chelate. The radiolytic results have been explained on the assumption of reduction of Fe(III) of the chelate by the available subexcitation electrons in addition to the e-sub(aq) or/and H atom (with fixed G values).
